Is moved in the horizontal direction to press and hold.

Vertically through a spring (not shown)
Vertically and rotatably arranged to be inserted into the axis of the direction , for example
Hard urethane cylindrical pressing tools 5, 5, 5 ', 5' are used.

Furthermore, the vertical pressing sandwich the left and right edges of the curved glass plate 1 substantially at an intermediate position away larger in the lateral than the walking beam 2 in the pressing tool 5, 5 'to dispose opposite to the front and rear A pressing member 9 made of, for example, MC nylon, which is rotatable by being inserted into a shaft (not shown) of the direction ;
9 'was arranged. (See FIG. 3) pressing tool 9, 9 'it
And the cylinder 7 connected to the pressing member 9 'and the pressing members 9', 9
Are slid left and right along a not-shown groove by rack pinions 8, 8 connected to the rack.

Steps for changing the shape and size of the curved glass plate 1
Swap , e.g. in the front and rear direction to fit different sizes
Adjustment devices for the pressing tools 5 and 5 and the rollers 4 and 4
Tsu bets, and the left and right adjustment cell of the pusher 9 for positioning adjustment
The adjustment is made by incorporating a mechanism (not shown) such as a ball screw configuration , for example.

As shown in FIG . 1, rollers 4, 4,
A support having 4 ′ and 4 ′ is disposed outside the walking beam 2 shown in FIG. 3, and is connected to a rod of the lifting cylinder 3 and is attached to the upper end of a concave base 11 that can move up and down. A shaft 12 and a fixed shaft 13 parallel to the walking beam were vertically installed.

The shaft base 12 has a concave base 1 sandwiching both ends of a pair of rollers 4, 4 'arranged in series in front and rear.
5 are slidably inserted and fitted at both ends. By the middle exterior surface of the base board 15 a projection 16 projecting downward is provided, and inserted engaging a notch (not shown) provided on the protrusion portion to the fixed shaft 13 of the lower, with respect to the shaft portion 12 The slidable base 15 is prevented from rotating.

On the other hand, the fixed shaft 1
The movable bodies 18 and 18 and the coil spring 20 are slidably inserted into the fixed member 3, and fixing rings 19 and 19 are fixed to the fixed shaft 13 via the coil spring .

Further, the guide rolls 2 are disposed obliquely below the front and rear fixing rings 19, 19, further away from the front and rear.
, And one end of the movable body 18,
Linked to 18, <br/> backward means of the base 15 by a rope 17 fixed to the stationary frame 23 the other end installing a walking beam 2,2, etc. hanging via guide rolls 22 21 Is configured .

The projection 16 is constantly pressed from both sides, and the gantry 11 is raised, that is, together with the base 15, the rollers 4,
4, 4 'and 4', the rope 17 pulls the movable bodies 18, 18 pressed by the coil springs 20, 20 in a direction against the pressing force, that is, compresses the coil spring 20, so that the protrusion 16 Is released from the pressing force, and the rollers 4, 4, 4 ', 4'
Is in a free state in which the movable body 18, which has slid along the fixed shaft 13, can slide along the shaft portion 12.

The coil springs 20, 20 are restored by the loosening of the ropes 17 due to the descent of the gantry 11, and the slidable rollers 4, 4, 4 ', 4' are moved to their original positions and pressed slidably. To lock.

In another embodiment shown in FIG. 4, an elongated hole is inserted into a fixed shaft 13 provided on
The arm 30 which is inclined and has a ring 32 attached to its tip is
The shaft portion 12 and the plate 33 are fixed to one end of the base 15 and fixed to a column 34 erected from the frame 23.
The ring to which the fixed shaft 13 is fixed
32 and a lower end of the inclined portion.
A Y-shaped guide 31 having an opening for holding and fixing the ring 32 is provided.

Hereinafter, the operation of the present invention will be described. The walking beam 2 as a carrier in the positioning device 10 descends together with the curved glass plate 1 on the beam, and
When the reversing movement is started by transferring the curved glass plate onto the reference numeral 4, 24, the reciprocating movement provided in the pressing tool 5, 5, 5 ', 5' and the gantry 11 by the operation of the associated lifting cylinders 3, 3 The means 21 and the like start to ascend integrally, and the rollers 4, 4, 4 ', 4' which have been waiting at the prescribed positions are also fixed rails 24, 2
4 approaches the lower surface of the curved glass plate 1.

The gantry 11 is raised at the same time as the rollers 4,
Movable bodies 18, 18 that press both sides of projections 16 provided on base 15 sandwiching 4, 4 ′, 4 ′ via coil springs 20
Is lifted, and the movable body 1
8, 18 are pulled.

The movable body 18 slides toward the fixed ring 19 while compressing the coil spring 20.
The movable body 18, which has slid along 3, can slide in the front-rear direction.

That is , as shown in FIG. 2, the rollers 4, 4, 4 ', and 4' integrated with the base 15 are also in a free state slidable along the shaft portion 12. When the curved glass plate 1 is supported in contact with the front and rear edges of the raised and bent glass, that is, the edges, the pressing cylinders 6, 6 actuate the pressing tools 5 ′, 5 ′ via the rack and pinions 8 ′, 8 ′. Is moved forward, the pressing tools 5 and 5 are moved rearward, and when the rear edge of the curved glass plate 1 is pressed, the roller 4 supporting the curved glass plate
4, 4 'and 4' also slide forward or backward integrally with the glass.

Subsequently, when the pressing members 9 and 9 ′ are moved to the left and right through the rack and pinion 8 by the left and right moving cylinder 7 which operates, for example, the curved glass plate 1 abutting on one pressing member 9 becomes the shaft portions 12 and 12. Rollers 4, 4,
It moves with the rotation of 4 ', 4' and the rotation of the pressing members 5, 5, 5 ', 5' which are axially attached to the vertical axis, and the left and right edges of the curved glass plate are held by the pressing members 9, 9 ' Then, the curved glass plate 1 is positioned in the left, right, front and rear directions by the pressing members 9, 9 'and the pressing members 5, 5, 5', 5 '.

Furthermore, it pressed and sucked into curved glass plate 1 which is positioned a suction pad (not shown) disposed above
After that , if the pressing cylinders 6, 6 and the left and right moving cylinders 7, 7 in operation are moved back to release the positioning, the curved glass plate 1 is transferred to the next joining step by raising the suction pad.

When the lifting cylinders 3 and 3 return, the base 1
When the ropes 1 and 11 are lowered, the coil springs 20, which have been compressed toward the fixing rings 19 and 19 together with the loosening of the rope 17,
.. Press the movable bodies 18, 18... With the restoring force, and if the projection 16 of the base is not moved between the pair of movable bodies, together with the bases 15, 15. Roller 4, moved back,
The positions of 4, 4 ', 4' are always constant.

In another embodiment shown in FIG . 4, the arm 30 fixed to the base 15 in FIG. 4 is moved by raising the gantry 11, that is, the rollers 4, 4, 4 ', 4' supporting the curved glass sheet 1. 3 held between the guides 31 and 31
2 rises and the rollers 4, 4, 4 ',
4 ′ is slidable, and the ring 32
Rolls on the guide 31 and moves the base 15 through the arm 30.
To the center side of the guide 31 arranged in a Y-shape,
The ring falls into the central depression and each roller 4, 4,
Positions 4 'and 4' are locked.

[0031]

According to the present invention, the front and rear edges of a three-dimensionally curved glass plate, that is, the edges are supported by a long cylindrical roller slidable and rotatable in the front and rear direction, and the four sides of the glass plate are further supported. At the time of positioning to press the edge of
When positioning in the front and rear transport direction, the roller slidable in the front and rear direction is integrated with the movement of the curved glass plate.
The roller rotates at the time of positioning in the left and right direction, so it always supports only at the edge without contacting the inner surface of the curved glass, so there is no abrasion or contamination on the inner surface of the glass plate , greatly improving yield. Contribute.

Further , after the positioning is completed , the rollers are always restored to the predetermined positions by the reciprocating means and stand by, thereby facilitating the configuration of a series of automation.
